Comparative Evaluation of Accuracy of Two Electronic Apex Locators In The Presence Of Various Irrigants: An In Vitro Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 11
Abstract
The purpose of this study was to compare the accuracy of Raypex 6 electronic apex locator (EAL), with actual root length and with the root length determined by a more commonly used EAL, the ProPex II. An additional objective was to determine the influence of commonly used endodontic irrigants on the accuracy of these electronic apex locators. This study will add knowledge to the existing literature and to the practioners using these EALs during WL determination in their day to day endodontic practice. A total of 100 extracted single rooted teeth were selected for the study. The teeth were randomly divided into 5 groups of 20 teeth each and Electronic working length was determined in the presence of various irrigants such as Dry root canals, Saline, 2% chlorhexidine, 17% EDTA, 2.5% NaOCl as the medium in the root canals. The results showed that the Accuracy of Raypex 6 and ProPex II was comparable in dry conditions, indicating that irrigating solutions do have an effect on the accuracy of EALs. Electronic root canal length measurements were unpredictable when saline was used as irrigating medium, almost all the values by both the EALs were short of apex when saline was used. These might be because of high electro conductivity of the saline solution. 2% chlorhexidine has been identified as the irrigating solution with least interference to the accuracy of EALs. Raypex 6 has been proved to have better accuracy and has least interference to irrigating mediums than ProPex II.
